Protective covers of hinges of equal angular speeds (CV JOINTS) carry out very important role, preventing hit of water and dirt in CV JOINTS. Hit on a protective cover of fuel or lubricant can lead to its destruction therefore it is recommended to wash out them water with soap.

Lift the car on the elevator, having hung out forward wheels. Turn a steering wheel to the right or to the left against the stop and turn a wheel. Examine rubber protective covers of hinges of equal angular speeds, squeezing them for disclosure of bends(fig. 2.26). Check them for existence of cracks which can lead to leak of lubricant and hit in water and dirt. Check a condition of collars of fastening, examine covers of internal hinges and casings on the other hand. Immediately replace the damaged protective cover.

Check a condition of hinges of equal angular speeds: having recorded a power shaft, try to turn a wheel. Repeat attempt, holding the internal hinge of equal angular speeds and turning a power shaft. Any noticeable side play indicates wear of the hinge, wear in grooves of a shaft or unscrewing of a lock nut of a shaft.
